openwrt guide could be improved

[ulfhermann]

The guide goes into quite some detail about the network configuration, but it left two rather nasty stumbling blocks for me:

1. The most important thing if you want to connect to the internet is getting the DSL configuration right. Rumor has it that the default "annex 'a'" actually never works. At least the guide should point to the importance of the "annex" setting and maybe link to https://openwrt.org/docs/guide-user/network/wan/isp-configurations (although that page is quite a mess). For me it was this:

config dsl 'dsl' option annex 'j' option tone 'bv' option firmware '/lib/fw.bin'

It can also be "annex 'b'", for example.

2. The wireless configuration is highly unusual as you have to set the encryption to "psk2+aes" in order to get WPA2. The guide should probably tell you that.

Also, the default network configuration file looks like there is a lot of cargo cult in there that can actually be dropped, but I haven't had the patience to find the useless bits, yet.

Can you please make a pull request for that? :)

@ulfhermann could you paste here your /etc/config/network.

I managed to get internet (1und1 vdsl) in the router but my PC connected via LAN has no internet so something with interfaces is messed up.

Here you go. It might not be an optimal solution. I don't understand all of it. This is for easybell, without VDSL. For VDSL you need some other settings in the "dsl" and maybe the "wan" section. I have no way to figure that out, though.

config interface 'loopback'

Yeah, mine looks completely identical:

config dsl 'dsl'
    option annex 'j'
    option tone 'bv'
    option firmware '/lib/fw.bin'

config interface 'wan'
    option ifname 'dsl0'
    option proto 'pppoe'
    option username 'xxxxxxxxxxxxxxxxxx'
    option password 'xxxxxxxxx'
    option ipv6 '0'
    option delegate '0'
    option keepalive '0' # the only difference

config device 'wan_dev'
    option name 'dsl0'
    option macaddr '......'

...

I used the trick with using my 2nd router for xDSL and connecting it with easy box through DSL(WAN) port to get Internet on my PC and the OpenWRT router so I can easier debug.

Actually today is my last day of the contract with 1und1 and from now on Deutsche Telekom will be mine provider so I reverted back to opened Vodafone firmware and will try with MIC settings because OpenWRT at least for the time being seemed not so stable.

Thanks for help!

The only setting I didn't try is in guide for Example VDSL configuration for Lantiq based devices:.

Did wifi work on openwrt? on my xdsl varian (Hardware R02) there was no wifi option :-/

i would like to turn it into an accesspoint with dhcp nothing more but there are no guides that work :-/

How can i bring up the wifi interface on the 904 easy box when i have openwrt?

Check this https://openwrt.org/docs/guide-user/network/wifi/basic

As further addition: Wifi works in AP but not in STA mode (you cannot connect to an existing network as a client).

The builds I tried had a nearly working sample config file (just disabled). This is how I changed it (using ssh and vi editor):

This might also be useful for you (the linked build works well for me):

https://github.com/majuss/easybox904/issues/17#issuecomment-718136959

In case you really just need an AP (with or without dhcp) you could also just keep the stock firmware. Only downside I noticed: no multicast (-> no iptv). With openwrt you can use the dsl-port as wan or lan.
